Definitions

  • the present invention is generally directed toward casings for deep well or gravity pressure reactor vessels. More particularly, the present invention is directed toward a reactor casing which will not readily fail when exposed to the divergent temperature fluctuations encountered in gravity pressure reactor vessels and which is likewise capable of enhanced angular deformation.
  • Such gravity pressure reactors often comprise a lengthy passageway or column, positioned inside a bore which has been excavated in the strata of the earth. It has been known to house the reactor in an outer casing which is then grouted in place in the bore. This outer casing serves to protect the reactor column from being affected by the surrounding strata, which often contains mineral rich fluids which may be detrimental to the reaction and/or corrosive to the reactor column. Further, the grouting material serves to prevent intermixing of fluids from different stratum and protect the casing from these fluids, as well as acting to prevent heat losses from the apparatus.
  • a containment casing for a gravity pressure reactor vessel is positioned in a bore in the earth and grouted in place.
  • the casing has a corrugated wall portion with an interior and an exterior side.
  • the casing has an inner liner which is supported by the interior side of the wall portion, and an outer liner supported by the grouting material.
  • the figure is a vertical section showing portions of two containment casing sections positioned in a bore hole.
  • a portion of a containment casing for a deep well or gravity pressure reactor vessel embodying the concepts of the present invention is generally indicated by the numeral 10 in the drawing.
  • Casing 10 includes a plurality of casing sections generally indicated by the numeral 11 which may be added one to the other in order to obtain any length of casing 10 required.
  • Casing 10 represents the outer casing of a reactor vessel which usually includes a plurality of concentric hydraulic columns within casing 10 as shown in U.S. Pat. Nos. 3,853,759 and 4,792,408 to which reference is made for whatever details are necessary to understand the present invention and the environment thereof.
  • Casing 10 is placed in a bore 12 in the earth and houses the reactor vessel within the surrounding strata "S".
  • casing 10 is shown as being positioned in bore 12 and grouted in place by grout material 13. This serves to prevent fluids from the surrounding strata S from interfering with the reaction taking place inside the reactor vessel. These fluids may be fresh water, salt water, oils and the like, and may even include different gases. Such mixtures may prove to be detrimental to the reaction, or they may prove to be corrosive to the reactor vessel and/or casing 10. Moreover, grout 13 also serves to reduce heat losses from the apparatus to the surrounding strata S.
  • Each casing section 11 of casing 10 includes a wall portion generally indicated by the numeral 20, which has corrugations 21, an interior side 22 and an exterior side 23. Because wall portion 20 has corrugations 21, it is capable of absorbing compression stresses such as may be introduced when casing 10 is caused to expand under the influence of thermal fluctuations. When the reactor is caused to be heated to temperatures as high as 900° F., as often encountered during normal operations, the corrugated nature of the wall portion 20 allows compensation for the attendant thermal expansion.
  • the corrugations 21 in wall portion 20 also provide for angular deviations in a section 11 of casing 10, such as may be necessary if bore 12 is not perfectly excavated. Thus, lateral deviations in bore 12 may be accommodated by bending of wall portion 20, which is possible due to corrugations 21.
  • Inner liner 24 is provided and is supported by the interior side 22 of the casing 10.
  • Inner liner 24 is of a thin-walled material which is strong enough to hold the hanging weight of the casing 10 during installation, and yet is thin enough that it can buckle and fail once exposed to high temperatures and then cooled.
  • a wall thickness of 1/8 inch with a diameter of 16 inches is sufficient to support a casing weighing approximately 600,000 pounds, but has virtually no compression strength and thereby will eventually fail.
  • a plurality of casing sections 11 may be placed one on top of the other in a bore 13, supported only by the strength of the inner liner 24.
  • the corrugations 21 are kept free of such material.
  • inner liner 24 will buckle and ultimately fail.
  • grouting material 13 has been allowed to set, providing support for the casing 10. Without inner liner 24 the corrugations 21 are thus free to flex as required.
  • an exterior liner 25 is provided on the exterior side 23 of the casing 10. Grout material 13 is thus prevented from engaging corrugations 21 as the material fills the space between the casing 10 and the strata S. Exterior liner 25 is preferably resistant to erosion and degradation caused by contact with fluids in strata S (water, oil and the like) and with the grout material. However, once the grout material 13 has set, it will not flow into the corrugations 21 should the exterior liner 25 fail. If failure does occur, the reactor is still protected by wall portion 20.
  • Exterior liner 25 is preferably thin walled and is fabricated so as to conform somewhat with the exterior side 23 of the casing 10.
  • the exterior liner 25 does not conform so as to mimic the corrugations 21, but is configured with slight indentations 26 at corrugations 21.
  • Indentations 26 enhance the seal, preventing strata fluids from intermingling by creating ring-like barriers at corrugations 21.
  • the exterior liner fail after the grout has set it is of no additional consequence to the system.
  • an inert filler material (not shown) could be positioned between exterior liner 25 and wall portion 20 thereby filling the space between corrugations 21 and liner 25.
  • an inert filler could be positioned between corrugations 21 and inner liner 24. Such would prevent a premature failure of the inner liner 24 or exterior liner 25.
  • the plurality of casing sections 11 may be joined as by a conventional coupling ring 30.
  • Coupling ring 30 threadably engages threaded upper and lower portions 31 of each casing section 11 so as to form casing 10.
  • Such coupling represents only one method of coupling a plurality of casing sections 11.
  • Other methods which are generally known in the art, could be used without departing from the spirit of this invention.
  • the reactor vessel With casing 10 in place the reactor vessel can be lowered within casing 10 concentrically spaced from inner liner 24.
  • the reactor vessel can then operate as described, for example, in U.S. Pat. Nos. 3,853,759 and 4,792,408.
  • the heat generated by the chemical reactions in the reactor vessel is better contained than the prior art due to the fact that casing 10 includes the three wall lamination or veneer, that is, it includes center wall 20, inner liner 24 and exterior liner 25 to better control convective heat losses.
  • the inside face of inner liner 24 may be calorized with aluminum or other material of high emissivity to reduce radiant heat losses.
  • the veneer construction permits a choice of materials such that a more economically constructed casing can be provided.
  • the thin exterior liner 25 need be constructed of a material which is highly resistive to the corrosive attack of the heated grout 13 and fluids from strata S.
  • the thicker corrugated center wall 20 thus can be constructed of a much less expensive material such as high strength steel.
  • the thin inner liner 24 may be constructed of a material of high emissivity of more expense than wall 20.
